dll question

ok, here's a stupid question...
i'm working in a bigger team now, and we're split up into two fractions:

I)c++/assembly
II) visual studio.net

now i'm in the c++ section and someone gave me this dll with a couple of classes and functions written in vb.net and told me to implement it in my program...

now here's the question: how can i use a vb.net dll in a c++ app?
loadfuntion() doesn't seem to work in this case, for it's not only functions i need but whole classes...

or could i re-compile it as a .lib file or something...?

i'm really lost here...

You need to get the person(s) that wrote the dll to make it COM support unless u are using vs C++ 7 /w .Net

I mean, I started off in VC 6.0, so i can port it to vs7 w/.net...
How can I use it there?
